Radial keratotomy was performed on six stumptail monkey eyes (Macaca speciosa) and 22 owl monkey eyes (Aotus trivirgotus). Changes in keratometry, specular microscopy, and tonometry have been studied postoperatively for three to six months. Sixteen radial incisions in stumptail monkey eyes resulted in a significant mean corneal flattening of 2.75 diopters (P less than 0.005). This effect was stable with a mean 2.50 diopters flattening remaining six months after surgery. Sixteen radial incisions in ten owl monkey eyes resulted in a much greater short-term effect, with a mean 10.50 diopters of flattening present at two weeks postoperatively. This flattening deteriorated over the observation period, and no significant effect was noted three months after surgery. A comparison of 8 vs 16 incisions on owl monkey eyes demonstrated that these two procedures are equally effective in initially flattening the cornea. Complications and side effects encountered included perforations, irregular astigmatism, corneal neovascularization, transitory increase in pachometry, and decrease in central corneal endothelial cell density in isolated cases.
对6只短尾猴（Macaca speciosa）眼和22只夜猴（Aotus trivirgotus）眼进行了放射状角膜切开术。术后三至六个月对角膜曲率计、镜面显微镜检查和眼压测量的变化进行了研究。短尾猴眼中的16条放射状切口导致角膜平均显著变平2.75屈光度（P小于0.005）。这种效果是稳定的，术后六个月仍平均保持2.50屈光度的变平。10只夜猴眼中的16条放射状切口产生了更大的短期效果，术后两周平均变平10.50屈光度。在观察期内这种变平情况恶化，术后三个月未观察到显著效果。对夜猴眼8条与16条切口的比较表明，这两种手术在最初使角膜变平方面同样有效。遇到的并发症和副作用包括穿孔、不规则散光、角膜新生血管形成、测厚仪暂时增加以及个别病例中央角膜内皮细胞密度降低。
